Meaning and Definition
A rare form of lightning that appears as a series of luminous, spherical segments resembling a string of glowing beads or pearls, persisting for a fraction of a second after a main lightning channel has faded.
The phenomenon is often associated with the decay or fragmentation of a linear lightning channel, creating a visually striking, segmented appearance. In scientific contexts, it is also referred to as 'pearl-necklace lightning' and is studied as a type of transient luminous event in the atmosphere.
Dialectal Variation

Differences
No significant lexical differences. Both varieties use the compound 'bead lightning'. The synonymous term 'pearl-necklace lightning' may be slightly more common in older British scientific literature.
Connotations
Purely descriptive and technical in both varieties.
Frequency
Extremely rare in general usage; frequency is equal and confined to specialist contexts in both regions.

FAQ
Frequently Asked Questions
No, they are distinct phenomena. Bead lightning is a very short-lived, linear-but-broken channel following a regular lightning stroke. Ball lightning is reported as a separate,持久 glowing sphere that moves independently and lasts much longer.
It is considered a very rare visual form of lightning. Most people will never see it, and even seasoned storm chasers may only record it a handful of times.
It is a manifestation of a lightning discharge that has already occurred. The primary stroke associated with it is the hazardous event. The beaded appearance itself is a residual optical effect and not a separate electrical hazard.
Scientific theories suggest it is due to irregularities in the diameter or ionization of the lightning channel as it cools and decays, causing some segments to remain luminous longer than others, creating the 'string of pearls' effect.
